I'm having the same issue. (iOS 12.4.7)

[mummymonkey]

Same thing here: iPad Air (Wi-Fi) running version 12.5.7

[CalebHeydon]

I got it to work by unplugging the cable and plugging it back in when it switches to the "right before trigger" step. The checkra1n app says unable to fetch bootstraps though. Does anyone know why this works?

[Oxyrobit]

I HAVE A SOLUTION: Use Checkra1n 0.10.2 ! :)
